1 Claim.

The invention relates to an hermetically sealed metal container for timefuses and the like.

An object of the invention is to provide a container of the above typewherein the ends which are attached to the body portion thereof areshaped so as to conform to and contact with the nose and butt endsrespectively of a time fuse to prevent endwise and lateral movement ofsaid fuse within the container.

A further object of the invention is to provide a container of suchconstruction that the portion of the ends attached thereto which contactwith the fuse, will yield to accommodate variations in the length offuses.

A still further object of the invention is to provide a container of theabove type, wherein the central formations in the ends, which con formto the ends of the fuse, are disposed within a plane tangent to thedouble seam joining the respective ends to the body of the container sothat containers may be placed one upon another for shipment or storagepurposes.

Referring to the drawing:

Fig. 1 is a side view showing the manner in which the containers may bestacked for shipment, one of said containers being in vertical sectionshowing a time fuse held within.

Fig. 2 is a top plan view of the container.

Fig. 3 is a sectional View of the container looking toward the bottomend.

Fig. 4 is an enlarged sectional view of the upper end of the containertaken at the double seam.

The invention relates to a container for hermetically packaging timefuses and the like. Thecontainer consists of a body portion of metalhaving its side edges joined by the usual type of lock and lap seam.Metal ends are double seamed to the container body by any standard typeof closing machine. One of said ends is depressed, forming a panel, andwithin the panel is a curved raised central dome portion which isadapted to conform to and contact with the nose end of a time fuse. Theother of said ends is depressed outwardly to form a retaining seat forthe butt end of the time fuse. The formations in the ends aredimensioned so as to always contact with the respective nose and buttends of the time fuse and prevent any endwise or lateral movement of thefuse within the. con tainer. The formations in the ends are eachdisposed within a plane tangent to the respective double seams joiningsaid ends of the container body so that one container may be stackedupon another for shipment or storage purposes.

Should there be slight variations in the lengths of time fuses, the endswill yield centrally thereof to accommodate the same.

Referring more in detail to the drawing, the improved container for timefuses is indicated at 5 5. A time fuse F having a nose end N and a buttend B, is shown within a container in Fig. 1 of the drawing. Thecontainer comprises a metal body portion 6 with metal ends 1 and 8double seamed thereto in the well known manner. The 10 double seam isindicated at 9 in the drawing. The end 1 of the container has adepressed portion l0 and centrally thereof has a curved raised domeshaped portion II which is adapted to contact with and conform to thenose end N of the time fuse. The other end 8 is provided with anoutwardly extending central depression I2 which forms a seat for thebutt end B of the time fuse. The diameter of the central depression 12is substantially the same as the outer diameter of the butt end B of thefuse. It can be readily seen from the drawing that with both endssecured to the container body, the parts H and I2 of the respective ends1 and 8 which conform to and contact with the nose and butt ends of thefuse, will hold the same from any lateral or endwise movement in thecontainer.

As further shown in Fig. 1 of the drawing, the outer extent of theformations II and I2 in the ends 1 and 8 are each within a plane tangentto the respective double seams so that one container may be stacked uponanother with the double seams contacting without interference from theformations II and I2. It will be further noted that the formations l and12 in the ends l and 8 are located centrally therein and the metal inthe region thereof will yield to accommodate slight Variations in lengthof time fuses.

From the above it will be apparent that a container has been devised forhermetically sealing time fuses, wherein the fuse is held from possibleendwise and lateral movement which might cause damage to the delicateparts thereof. The container being hermetically sealed, protects thefuse from moisture which might damage or render the fuse useless. Also acontainer has been devised which may be stacked for shipment or storagein a comparatively small space, as there are no projections on theexterior thereof to prevent the close packing of the same. The containeras described lends itself to vacuumization or filling with an inert gaswhich would prevent deterioration of the material contained in thefuses.

It is obvious that minor changes in the details of construction andarrangement of the parts may be made without departing from the spiritof the invention as set forth in the appended claim.

I claim: 7

An hermetically sealed metal container for time fuses and the likecomprising a body portion, a top end seamed thereto, saidrend having thecentral recess thereof shaped to conform to the nose of said fuse withthe portions of the end between said recess and the seam substantiallyflat and parallel to a plane containing the seam, and a bottom endportion seamed thereto and having a central recess shaped to conform tothe bottom end of the fuse, said bottom end between said last-namedrecess and the seam being substantially flat and parallel to the planeof said seam, said ends being positioned so as to yieldingly contactwith the nose and the bottom end of the fuse for preventing the samefrom the lateral endwise movement in the container.
